Key Principles of Diagnostic Imaging
- Do no harm
- use DI only when you are positive findings will alter the intervention
- always get at least 2 views
- small component of larger picture
- these are special tests
- consider diagnostic yield
- conventional radiographs generally first
- use shielding when possible
- lowest dose view
